The new, pocket-sized 4:1 IR Thermometer with NCV Detector & Flashlight (VR40) [Patent Pending] from General Tools & Instruments (General®) embodies innovation in several ways that benefit technicians, contractors and electricians. As an instrument with multiple functions—Infrared Thermometer (IRT), Non-Contact Voltage (NCV) detector and flashlight—the VR40 offers more versatility and utility than other products on the market, increases efficiency on the job and gives users more bang for their buck. Plus, its size makes it the perfect field tool, whether at the top of a ladder or in a dark crawl space. The VR40’s integral IRT provides a safe and reliable way to measure surface temperatures, so it’s ideal for HVACR professionals who need to determine the temperature of heating or cooling coils, or detect overload currents in motors, electrical conduits and junction boxes. Temperature readings are displayed in Fahrenheit or Celsius (-4° to 626°F/-20° to 330°C) on a four-digit LCD and are automatically held for 15 seconds. Unlike other NCV detectors with only one sensitivity level— meaning the ability to detect just one range of voltages—General’s VR40 offers four sensitivity levels chosen to optimize voltage detection over four practical ranges (12 to 25VAC, 70 to 125VAC, 150 to 240VAC, 250 to 600VAC). The ability to detect the presence of 12VAC without direct contact comes in handy when troubleshooting branch circuits, as well as process plant or industrial automation systems and equipment, and hardwired thermostats. The VR40’s lower sensitivity levels are valuable for taking the guesswork out of identifying the “hot” wire in a bundle. The instrument’s audible and visual alarms make it immediately evident when voltage is detected. And because the tip of the VR40 can fit in the slots of 110VAC receptacles, it also indicates whether the receptacle is wired correctly or in reverse.
